Ok. Going back to Dec 17 when I was in camp & could get pics of graphs right after a system crash while using a 4.5kW water heater.
I see the Absorb Charging Voltage followed by a Float Charging Voltage then sunset. Looks like batteries settled at @ 50.8 V or 85%. Right off the bat, I think our Absorb time needs upping. currently set at 1hr, should be 2-3hrs to really get batts fully charged. Voltage should settle at 52 when charge voltage is removed.
The gradual voltage drop overnight looks reasonable. But I don't understand why it takes so long to start and Absorb charge once it's light out.
Absorb is basically a fast charge. Float is more like a trickle charge.
